The carbon won't really splinter if you use the dremel....I used the tape as my guide. I do recomend that you use the hacksaw with a fine tooth blade to cut away the packing.....and be careful to not get those fibers on your skin....very itchy. If so wash your self with cold water. (Cold water keeps your pores closed so the little fibers won't get in). All you really have to do is just go in with the right mind set and do it.
